Constructor Detail

DoubleBuffer

public DoubleBuffer(Size allocate_size)

Constructs a DoubleBuffer, allocates the buffer.

Parameters:

allocate_size - the buffer size.

Method Detail

get

public double get(int x,
                  int y)
           throws java.lang.IndexOutOfBoundsException

Gets pixel value of a specified position.

Parameters:

x - the x position.

y - the y position.

Returns:

the pixel value of the position.

Throws:

java.lang.IndexOutOfBoundsException - if specified position is out of the image area.

set

public void set(int x,
                int y,
                double value)
         throws java.lang.IndexOutOfBoundsException

Sets pixel value of a specified position.

Parameters:

x - the x position.

y - the y position.

value - the value to set.

Throws:

java.lang.IndexOutOfBoundsException - if specified position is out of the image area.

getValue

public double getValue(int x,
                       int y)
                throws java.lang.IndexOutOfBoundsException

Gets pixel value of a specified position.

Overrides:

getValue in class Buffer

Parameters:

x - the x position.

y - the y position.

Returns:

the pixel value of the position.

Throws:

java.lang.IndexOutOfBoundsException - if specified position is out of the image area.

setValue

public void setValue(int x,
                     int y,
                     double value)
              throws java.lang.IndexOutOfBoundsException

Sets pixel value of a specified position. The value is forcedly converted into the data type of image buffer.

Overrides:

setValue in class Buffer

Parameters:

x - the x position.

y - the y position.

value - the value to set.

Throws:
